An amplifier (200) comprises: an input stage (101) for receiving incoming signals; a high gain stage (110) coupled to the input stage (101) and providing driving signals in response to the incoming signals to an output driver stage (120); and an output terminal coupled to the output driver stage (120). The output driver stage (120) comprises a high side driver circuit (105) having a first terminal receiving a first driving signal pdrive from the high gain stage (110), a second terminal coupled VDD through a first voltage drop (201), and a third terminal coupled to the output terminal (107) of the amplifier (200).
